In the Old Testament, God stated, "Remember the Sabbath day to keep it holy. Six days you shall labor and do all your work, but the seventh day is a Sabbath of the Lord your God; in it you shall not do any work, you or your son or your daughter your male or your female servant or your cattle or your sojourner who stays with you," (Exodus 20:8-10, NASB). It was the custom of the Jews to come together on the Sabbath, which is Saturday, cease work, and worship God. Jesus went to the synagogue on Saturday to teach (Matt. 12:9; John 18:20) as did the apostle Paul (Acts 17:2; 18:4). So, if in the Old Testament we are commanded to keep the Sabbath and in the New Testament we see Jews, Jesus, and the apostles doing the same thing, then why do we worship on Sunday?
First of all, of the 10 commandments listed in Exodus 20:1-17, only 9 of them were restated in the New Testament. (Six in Matt. 19:18, murder, adultery, stealing, false witness, honor parents, and worshiping God; Rom. 13:9, coveting. Worshiping God properly covers the first three commandments) The one that was not reaffirmed was the one about the Sabbath. Instead, Jesus said that He is the Lord of the Sabbath (Matt. 12:8).
In creation, God rested on the seventh day. But, since God is all powerful, He doesn’t get tired. He doesn’t need to take a break and rest. So, why does it say that He rested? The reason is simple: Mark 2:27 says, "The Sabbath was made for man, and not man for the Sabbath." In other words, God established the Sabbath as a rest for His people, not because He needed a break, but because we are mortal and need a time of rest, of focus on God. In this, our spirits and bodies are both renewed.
The OT system of Law required keeping the Sabbath as part of the overall moral, legal, and sacrificial system by which the Jewish people satisfied God’s requirements for behavior, government, and forgiveness of sins. The Sabbath was part of the Law in that sense. In order to "remain" in favor with God, you had to also keep the Sabbath. If it was not kept, then the person was in sin and would often be punished (Ezek. 18:4; Rom. 6:23; Deut. 13:1-9; Num. 35:31; Lev. 20:2, etc.).
But with Jesus’ atonement, we no longer are required to keep the Law as a means for our justification. The requirements of the Law were fulfilled in Christ. We now have rest from the Law. We now have "Sabbath", continually.
Are we free to worship on Sunday?
Within the New Testament is ample evidence that the seventh day Sabbath is no longer a requirement.
"One man regards one day above another, another regards every day alike. Let each man be fully convinced in his own mind. 6 He who observes the day, observes it for the Lord, and he who eats, does so for the Lord, for he gives thanks to God; and he who eats not, for the Lord he does not eat, and gives thanks to God," (Rom. 14:5-6).
The entire section of Rom. 14:1-12 is worth careful study. The instructions here are that individuals must be convinced in their own minds about which day they observe for the Lord. If the seventh day Sabbath were a requirement, then the choice would not be mans’, but God’s. To me, this verse is sufficient to answer the question beyond doubt. Furthermore,
"Therefore let no one act as your judge in regard to food or drink or in respect to a festival or a new moon or a Sabbath day— 17things which are a mere shadow of what is to come; but the substance belongs to Christ." (Col. 2:16-17).
Notice the time sequence mentioned in Col. 2:16-17 above. A festival is yearly. A new moon is monthly. A Sabbath is weekly. No one is to judge in regard to this. The Sabbath is defined as a shadow, the reality is Jesus. Jesus is our Sabbath. So, if someone is judging you because you worship on the Sabbath, they are wrong. Likewise, if you regard Sunday above Saturday (Rom. 14:5-6), all you need to do is be convinced in your own mind that that is alright.
Is there any evidence in the NT that Christians met on Sunday?
"And on the first day of the week, when we were gathered together to break bread, Paul began talking to them, intending to depart the next day, and he prolonged his message until midnight," (Acts 20:7).
The first day of the week is Sunday and this is the day the people gathered. This passage can easily be seen as the church meeting on Sunday, though it does not necessitate it. It has two important church functions within it: breaking bread (communion) and a message (preaching/teaching). Additionally, Luke included the Roman system as well as the Jewish system of counting days. The Jewish system was sundown to sundown. But Luke also used the Roman system: midnight to midnight (Luke 11:5; Acts 16:25; 20:7; 27:27). This is a subtle point that shows the Jewish Sabbath system was not exclusively used by Luke.
If the Sabbath was mandatory, why the use of the non-Jewish system?
"Now concerning the collection for the saints, as I directed the churches of Galatia, so do you also. 2On the first day of every week let each one of you put aside and save, as he may prosper, that no collections be made when I come," (1 Cor. 16:1-2).
Notice here that Paul is directing the churches to meet on the first day of each week and put money aside. It would seem that this is tithing. So, the instructed time for the church to meet is Sunday, the first day of the week and it is that day the Galatians were to set money aside collections. Is this an official worship day set up by the church? You decide. Does this verse apply to Christians today? It most certainly does.
"I was in the Spirit on the Lord’s day, and I heard behind me a loud voice like the sound of a trumpet, 11saying, "Write in a book what you see, and send it to the seven churches: to Ephesus and to Smyrna and to Pergamum and to Thyatira and to Sardis and to Philadelphia and to Laodicea," (Revelation 1:10-11).
The New Bible Dictionary says regarding the term, ‘The Lord’s Day’ in Rev. 1:10: "This is the first extant occurrence in Christian literature of "te kuriake hemera." The adjectival construction suggests that it was a formal designation of the church’s worship day. As such it certainly appears early in the 2nd century" (Ignatius, Epistle to the Magnesians, 1. 67).
In many churches today, the term "The Lord’s Day" is used to designate Sunday, the same as it was in the second century.
I hope this is evidence enough to show you that the Bible does not require that we worship on Saturday. If anything, we have the freedom (Rom. 14:1-12) to worship on the day that we believe we should. And, no one should judge us in regard to the day we keep. We are free in Christ and not under law, (Rom. 6:14).
The Seventh Day Adventists have every right to worship on the Sabbath and they should if they are convinced that is the right thing to do. However, if any member of any church were to require a person to worship on the Sabbath as a sign of "true" Christianity or "true" redemption, then that is wrong. According to Rom. 14:1-12, we are free.
Additionally, Sunday is the day that the Lord Jesus rose from the dead. The Jewish people who had rejected Jesus continued to worship on Saturday, the Sabbath. But it was the Christians who celebrated Jesus' resurrection and this was most probably the driving force to gather on the first day of the week.
